摘要
以三光气和取代苯胺为原料，合成10种取代苯异氰酸酯。并且对原料的摩尔比、反应溶剂和引发剂等因素对收率的影响进行了研究，研究表明，当三光气与苯胺的摩尔比为1：2，引发剂为三乙胺，溶剂为甲苯、1，2-二氯乙烷或者乙酸乙酯，反应时间为3．5～5．5h的情况下，取代苯异氰酸酯产率为69．7％-92．4％。
Ten substituted phenyl isocyanates were obtained with bis（trichloromethyl） carbonate and substituted aniline. Factors such as mole ratio of raw materials, the solvent and the initiators were also studied. The results show that the yield of substituted phenyl isoeyanates are 69.7% - 92.4% when the reaction conditions are as follows ： the mole ratio of bis （trichloromethyl） carbonate to substituted aniline is 1：2, the initiator is triethylamine, the solvent is toluene, 1,2-dichloroethane or ethyl acetate,the reaction time is 3.5 - 5.5 h.
